Published Engineering viruses to kill deadly pathogens
(via sciencedaily.com) Original source Antimicrobial resistance is an urgent and growing global crisis. Researchers are exploring phages, viruses that infect bacteria, as a possible solution. In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. The process can also be used to produce more phage variants for further exploration.
Published Researchers discover new ways to excite spin waves with extreme infrared light
(via sciencedaily.com) Original source Researchers have developed a pioneering method to precisely manipulate ultrafast spin waves in antiferromagnetic materials using tailored light pulses.
Published When and how immune cells decide to form pathogen memories
(via sciencedaily.com) Original source During infection, reversible switch permits flexible formation of memory T cells, long-lived blood cells that can remember pathogen encounters and respond upon reinfection.
Published Using computers to design proteins allows researchers to make tunable hydrogels that can form both inside and outside of cells
(via sciencedaily.com) Original source New research demonstrates a new class of hydrogels that can form not just outside cells, but also inside of them. These hydrogels exhibited similar mechanical properties both inside and outside of cells, providing researchers with a new tool to group proteins together inside of cells.
Published A green alternative for treating Streptococcus iniae bacteria in hybrid striped bass
(via sciencedaily.com) Original source Scientists have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.
Published DNA particles that mimic viruses hold promise as vaccines
(via sciencedaily.com) Original source Using a DNA-based delivery particle, researchers created a vaccine that can induce a strong antibody response against SARS-CoV-2.
Published New breakthroughs for unlocking the potential of plasmonics
(via sciencedaily.com) Original source Plasmonics are unique light-matter interactions in the nanoscale regime. Now, a team of researchers has highlighted advances in shadow growth techniques for plasmonic materials, which have the potential to give rise to nanoparticles with diverse shapes and properties. They also introduce a method for large-scale production of nano-rotamers of magnesium with programmable polarization behavior, opening avenues for novel research applications.
Published Resin destroys coronavirus from plastic surfaces
(via sciencedaily.com) Original source Researchers are currently developing anti-viral surfaces to decrease the spread of infectious diseases. A recent study found that a resin ingredient is effective against coronaviruses and strongly decreases their infectivity on plastic surfaces.
Published A faster, more efficient imaging system for nanoparticles
(via sciencedaily.com) Original source Scientists have developed a new system for imaging nanoparticles. It consists of a high-precision, short-wave infrared imaging technique capable of capturing the photoluminescence lifetimes of rare-earth doped nanoparticles in the micro- to millisecond range.
Published Tomato juice's antimicrobial properties can kill salmonella
(via sciencedaily.com) Original source New research shows that tomato juice can kill Salmonella Typhi and other bacteria that can harm people's digestive and urinary tract health.
Published Researchers propose AI-guided system for robotic inspection of buildings, roads and bridges
(via sciencedaily.com) Original source Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that's likely to get worse, according to experts, because it's just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers are trying to give robotic assistants the tools to help inspectors with the job.
Published Structural color ink: Printable, non-iridescent and lightweight
(via sciencedaily.com) Original source A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This development enables non-fading structural colors that do not depend on the viewing angle and can be printed. The material has a low environmental and biological impact and can be applied extremely thinly, promising significant weight improvements over conventional paints.
Published Gut microbiota influence severity of respiratory viral infection
(via sciencedaily.com) Original source The composition of microbiota found in the gut influences how susceptible mice are to respiratory virus infections and the severity of these infections.
Published 'Genomic time machine' reveals secrets of our DNA
(via sciencedaily.com) Original source Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.
Published Probiotics promote weight loss in obese dogs
(via sciencedaily.com) Original source New research demonstrates how probiotics can reshape the gut microbiome and energy metabolism in dogs.
Published Researchers control biofilm formation using optical traps
(via sciencedaily.com) Original source Researchers showed that biofilm formation can be controlled with laser light in the form of optical traps. The findings could allow scientists to harness biofilms for various bioengineering applications.
Published Cosmic building blocks of life discovered through the electron microscope
(via sciencedaily.com) Original source Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.
Published How obesity dismantles our mitochondria
(via sciencedaily.com) Original source Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.
Published Researchers map genome for cats, dolphins, birds, and dozens of other animals
(via sciencedaily.com) Original source Researchers mapped genetic blueprints for 51 species including cats, dolphins, kangaroos, penguins, sharks, and turtles, a discovery that deepens our understanding of evolution and the links between humans and animals. The researchers developed novel algorithms and computer software that cut the sequencing time from months -- or decades in the case of the human genome -- to a matter of days.
Published Soap bark discovery offers a sustainability booster for the global vaccine market
(via sciencedaily.com) Original source A valuable molecule sourced from the soapbark tree and used as a key ingredient in vaccines, has been replicated in an alternative plant host for the first time, opening unprecedented opportunities for the vaccine industry.
